Patented Oct. 23, 1934 UNITED STATES PATENT OFFICE This invention relates to fittings for a lavatory andmore particularly to a dental fitting to pro vide clean water and to remove waste water.

An object of this invention is to provide a fit- 'ting which is so constructed that water may be obtained for use in cleaning the teeth and the waste water may be. discharged through the drain pipe of the wash basin to which the device is attached.

A further object of this invention is to provide a combination fitting which can be combined with a Wash basin and connected to the source of water supply for the basin and also to the waste connection for thebasin so that suitable water of desired temperature can be supplied at the desired point.

A still'further object of this invention is to provide a fitting of this kind wherein the draining means for the wash basin also acts as the meansfor operating the valve embodied in the device so that the water may be supplied to either the basin or the spout.

The aboveand various other objects and advantages of this invention will in part be described and in part be understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing wherein:

Figure 1 is a vertical section partly in detail of a device constructed according to the embodiment of this invention.

Figure 2 is a sectional view taken on the line 2--2 of Figure 1.

Figure. 3' is a sectional View taken on the line 3--3 of Figure 1.

Referring to the drawing wherein like numerals of reference designate corresponding parts throughout "the several views, the numeral 10 designates generally a basin provided with a base 11 which is mounted on a supporting member 13.

The basin in the present instance is constructed with a relatively small central portion or stem 12, which terminates in a spout 14 extending horizontally from the base' 11. The-base 11 has a bore 15 extending vertically therethrough and a pipelfi is threaded into the lower portion of the base and is looked as by a nut 17 to the spout 14. The pipe 16 is adapted to be connected to a source of water supply. The spout 14 has a channel or passage 18 communicating with the bore .15 of the base 11, so that the water from the pipe 16 will flow through the spout or neck 14. The basin 10 has disposed on one side thereof a channel or passage 19 which opens, as at 20, in the mm 21 of the basin and opens in the direction of the body of the basin so that the water or liquid flowing upwardly in the channel 19 will be directed into the interior of the basin 10. The lower end of the passage 19 communicates with I, the bore 15 preferably at a point diametrically opposed to the channel 18 in the spout or spigot In order to regulate the flow of water or liquid through either the spout 14 or the passage 19,

I have provided a substantially cylindrical valve 22 which is disposed in-thebore 15. This valve 22 has an opening 23 which, upon 'turning of the valve 22 in one direction, is adapted to discharge the water from thepipe 16 into the channel 18. I The valve 22 also has a second opening 24'which 7 j is adapted to permit, upon turning of the valve 22, the discharge of water into "the passage 19. The lower end of the valve '22 preferably engages the upper endiof the pipe 16 and'the'lower'end is provided with anarcuate recess 25 in which is received a pin 26 secured to the base 10. The,

- pin 26 acts as a limiting means to limit the turning of the valve 22 or permitting sufiicient rotation thereof to bring the desired openings in the valve into register with the desired discharge channel. lower portion of the basin 10 and engages the A flanged cap 2'7 is threaded into the upper end of the valve 22 so as to hold this valve 22 against longitudinal movement in the bore 15 while permitting rotary movement. A gasket or washer 28 is interposed between the cap 27 and p the upper end of the valve 15 so as to seal the valve in the lower portion of the basin 10.

The cap 2'7 has an opening 29 centrally there- 'through in which a combined valve operating member and drain 30 is slidably and rotatably received. The valve operating and drain member 30 comprises a length of pipe substantially smaller in diameter than the pipe 16 and this hollow member 30 is provided with a knob or handle 31 on the upper end thereof.

The hollow drain member andvalve operating member 30 at a point within the base 11, is provided With aplurality of outstanding radially arranged-pins 32'which engage in vertical -;grooves 33 provided in theinnersurface of the valve 22'. These pins 32 permit vertical movement of the member 30 for a distance of substantially the length of the valve 22 so that the drain openings 34 in the upper end of the member 30 can be positioned at a point adjacent the upper surface of the cap 27 which constitutes the bottom of the basin 10 or the drain openings 34 may be raised to a point spaced upwardly from the bottom of the H basin 10. In the raised position of the openings 34, the valve 22 is preferably closed as to the passage 19.

In the use and operation of this device, when it is desired to discharge water through the 5 spigot 14, the valve 22 is turned, as shown in Figures 1 and 2, so that the discharge opening 23 in the valve will register with the passage 18 in the spout 14. At this time, the passage 19 is closed so that no water will be discharged through the passage l9. If it is desired to discharge water into the basin 10 through the passage 19, the valve 22 is turned so that the opening 24 will register with the lower end of the passage 19, thereby cutting off the passage 18. During the use of the valve 22, the valve operating member and drain 30 may be either at the lowermost point shown in full lines in Figure l, or may be raised to the point shown in dotted lines in Figure 1. Where the valve operating member and drain 30 is at the lowermost point, all water received in the basin 10 will flow out through the drain openings 34 and down through the pipe 30 which is adapted to be connected to a suitable carry-off pipe.

The valve operating member 30 in the present instance also operates the drain plug connected to the wash basin on which the basin 10 hereinbefore described is mounted, Preferably, the support13 is the top or rim of the wash basin and the Valve operating member 30 is the vertically movable drain plug operating member used in the type of Wash basins where the plug is raised by an operating member disposed at one side of the basin. It will, therefore, be apparent that ;the drain plug operating member for the wash basin will also serve the purpose of providing a drain means for the basin 10 which is preferably constructedof the same design and material as the escutcheons on the lavatory handles.

It will also be apparent from the foregoing that the device hereinbefore described will increase the sanitation of the wash basin in that the basin 10 will provide a means for receiving the Waste water during the washing of the teeth and -the rinsing of the mouth, whereas the wash basin 1 ;;,-ing a passage therethrough, a basin extending above the base, means for connecting the base to a source of liquid supply, a two-way valve carried by the base, means carried by the basin and communicating with the passagein the base to discharge the liquid in the upper portion of the basin and valve operating means extending upwardly into the basin.

A fitting as set forth, comprising a base having a passage therethrough, means for connecting the base to a source of liquid supply, a spout carried by the base and communicating with the passage therein, a basin extending above the base, means carried by the basin and communicating with the'passage to discharge the liquid in the r upper portion of the basin, a two-way valve car- 3. A fitting as set forth, comprising a. base having a passage therethrough, means for connecting the base to a source of liquid supply, a basin extending above the base, a spout extending laterally of the base and communicating with the passage therein, means carried by the basin for discharging the liquid in the upper portion of the basin, a two-way valve carried by the base, a hollow valve operating member extending upwardly through the basin, and means for connecting the valve operating member to a carry-off means.
